This ELAN sew-through button is a reliable finishing detail for everyday mending and handmade pieces, suitable for shirts, knitwear, children’s wear, bags, costumes, and light home décor. Each card contains 3 buttons at 15 mm (5/8 in), with a classic 2-hole face that sits flat on the fabric and stitches on quickly by hand or with a sewing machine. Match the diameter to the existing buttonhole and use firm, even stitches so the closure wears comfortably and stays secure through regular use.
